For PCs to share network resources and/or Internet access without connecting with an Ethernet cable, install a wireless client adaptor in each PC. The G-302 has a removable antenna perfect for any type of application. If you're the average user then the included antenna should suffice. But if you require something a little more robust, then the reverse SMA connector is perfect for any extra gain antenna. Simply screw on any antenna with an SMA connector and you're ready to go. Finally it's IEEE 802.11g/b certified for maximum compliancy to all other IEEE802.11g/b certified devices!
